Short answer: a sliding glass door that drags or jumps its track can usually be fixed for an estimated $150–$700 with new rollers and track work. Replacing a two-panel slider costs about $1,800–$3,200 in non-impact glass and $3,000–$6,000 impact-rated, installed.
Repair first
Most sliding door complaints come down to a handful of parts.
- Rollers. The wheels under the panel flatten or seize. New ones, adjusted to the right height, fix most hard-to-open doors.
- Track. Aluminum track wears and corrodes, especially near the beaches. It can be repaired or covered with a stainless cap.
- Locks and handles. Replacement hardware is available for most common doors.
- Weatherstripping and sill leaks. Worn pile strips and clogged weep holes let wind-driven rain in under the door.
- Fogged or broken glass. A new sealed glass panel can go into the existing door panel.
When a new door makes sense
Replace rather than repair when the frame is corroded through, when the door leaks from the frame rather than the sill, or when you want impact protection on the biggest opening in the house. A new door is also the time to change configuration: a two-panel slider can become a three-panel, or a slider can become a pair of French doors where the room allows.
Sliders, French doors and lanai openings
Two-panel sliders around six feet wide are the most common size in St. Pete homes. Wider three- and four-panel sliders suit open-plan rooms onto a pool or lanai. Hinged French doors give a full-width opening and a more traditional look. All of them come in non-impact and impact versions, with clear, Low-E or tinted glass.
Installation and the permit
A replacement door is permitted like a window. We remove the old frame, check the opening and the slab edge beneath the sill, set the new frame level and plumb, anchor it as its Florida Product Approval specifies, and seal the sill so rain drains out instead of in. Most doors are swapped in a day.

Questions
Why is my sliding door so hard to open?
Nine times out of ten the rollers have worn flat or the track is full of grit and corrosion. New rollers and a cleaned or capped track usually make an old door glide again for a fraction of the cost of replacement.
Does a new sliding door need to be impact-rated?
In St. Petersburg a new door, like a new window, has to be impact-rated or protected by approved shutters, because the city is in the wind-borne debris region. Large doors are often the weakest opening in a house, so many owners start their impact upgrade there.
Can you match a new door to my windows?
Yes. We can order the door in the same frame color, glass tint and grid pattern as the windows, whether those are new or ones we fitted earlier.
